- You're a bit too pessimistic here. I'm using such a driver to run all
- four COM ports and it does 2400 bps with a 16450 and 19200 bps with a
- 16550A. 19200 bps gets a bit unreliable under load, but it's still
- acceptable for Zmodem. I'm polling at 300 Hz and it doesn't lower
- system performance very noticeably.

- Is this on Linux? How are you polling at 300Hz, when the system clock
- ticks at 100Hz?
